Product name: Spot Welder Machine Accessory

Power supply voltage: 12V-15V

Working current: 100-200A

Weight: 130g

Package size: 14×9×3cm


1. The smart spot welding program is added, the trigger switch is abandoned when the bottom is removed, and the program is used to automatically control the spot welding action. When the welding pen touches the nickel sheet, the spot welding pulse is automatically output! Do whatever you want! No need to press the switch! At the same time, the delay is abandoned Spot welding mode! Leave everything to the program, free your hands, and truly achieve the effect of clicking on what you think of!

2. Upgrade from the original 3rd gear to the current 5th gear. This can better adapt to different batteries, batteries with poorer performance can also be spot welded, and also adapt to more convenient scenarios, different thicknesses of nickel sheets There can be more stalls to choose from!

3. The structure of the board has been optimized, and the circuit design is more reasonable! The driving part of the MOS tube of the board is thickened and tinned, which effectively reduces the resistance and increases the over-current capability!

4. Added 4 screw holes, suitable for installation in a small box,

5. This spot welding machine circuit board can be used to weld lithium batteries such as 18650/26650/32650. Advantages: portable, stable, reliable, and durable. The cost is low, you have your own car starter battery, or a high-power battery pack, and you can use it after connecting it! It saves the production cost!

6. Users need to prepare their own 12V battery for power supply, and the welding current is about 100A~200A, which is easy for common 0.1mm~0.15mm nickel-plated sheet welding. Please make sure your battery can have a current greater than 100A, otherwise you will not be able to weld!
